rings of saturn

I recently came across a story about NASA's Cassini spacecraft ~ the agency's fourth mission to explore Saturn, but the first to really examine the planet's rings and moons. The Cassini website is incredibly addictive and completely fascinating ~ click through the hundreds of photographs and read about the mission. The photographs are so clear and real ~ and at the same time so beautifully abstract.
